How you missed the mantra on the soekris lists of:
"Your power supply is inadequate" for 99.9% of the reboot/reset
problems is beyond me...
12v/1A is MINIMUM. You could power it from a PC's power
supply at 10A and it would draw only what it needs.
Note too that the soekris can take up to 56V via PoE (4511/4521)
and the 4501 can accept perhaps 26V on the DC-in socket. Its
documented. A 20v power supply works fine.
WEP will slow down wireless but I thought it never reached the
computer. I know that lots of IPSec will beat a soekris into
submission without a coprocessor. SCP involves encryption and
WILL beat up the CPU. Perhaps you can test with RCP.
When debugging, however, simplify:
Try also TTCP as a bandwidth measurement. It can blast a 1GB
file and track how long it takes and at what speeds.
It won't encrypt, so most of the work will be passing packets.
